"Our transmitting antenna beam must be monitored in real time and precisely directed toward the receiving antenna. To achieve this, we have developed a high-precision closed-loop control system based on reverse beam guidance. When the receiving antenna sends out a guiding signal, the transmitting antenna can promptly capture it and instantly calculate the position and angular attitude of the receiving antenna, thereby ensuring accurate beam pointing."

"This means that most of the beams emitted by our transmitting antenna can be precisely captured by the receiving antenna, with very little energy wasted. In addition, our overall output power has reached the kilowatt level, which is enough to run a household air conditioner. It can also easily cover everyday needs such as cooking, boiling water, or other domestic uses."

China's ongoing Sun Chasing project, led by Xidian University in northwest China's Shaanxi Province, has achieved a breakthrough in transmitting energy to multiple moving targets simultaneously, marking progress toward building a space solar power station.

The project, named "Zhuri" in Chinese and launched in 2022, is designed to one day send energy back to Earth or spacecraft.

Its latest upgrade has shifted from one-to-one fixed transmission to one-to-many dynamic supply, enabling precise power delivery to multiple fast-moving targets.

Researchers said the challenge of the upgraded system was to keep beams locked on moving targets without losing signal.

"Our transmitting antenna beam must be monitored in real time and precisely directed toward the receiving antenna. To achieve this, we have developed a high-precision closed-loop control system based on reverse beam guidance. When the receiving antenna sends out a guiding signal, the transmitting antenna can promptly capture it and instantly calculate the position and angular attitude of the receiving antenna, thereby ensuring accurate beam pointing," said Qian Sihao, associate professor at the School of Electromechanical Engineering of the university.

In simple terms, the system can track targets and make real-time corrections during transmission, enabling dynamic power supply to multiple moving devices.

To prevent damage from misaligned beams, key components were upgraded with gallium nitride diodes, improving tolerance to high-power fluctuations.

Outdoor tests showed the system could deliver 1,180 watts of output power at a distance of 100 meters, with DC-to-DC transmission efficiency rising to 20.8 percent and beam collection efficiency reaching 88 percent.

"This means that most of the beams emitted by our transmitting antenna can be precisely captured by the receiving antenna, with very little energy wasted. In addition, our overall output power has reached the kilowatt level, which is enough to run a household air conditioner. It can also easily cover everyday needs such as cooking, boiling water, or other domestic uses," Qian added.
